Even with the technology in year 2012 and using all the resources (money, man power and materials) of the whole population on Earth, do you really think we can build something up to 15,000m? Do you really think that the Tower of the Babel in the old days can reach the sky and reach the Heaven?

So my question becomes: Why bother to interrupt people's work, for God knows that it is impossible for human beings to build anything tall?

My other question is that if you read Genesis 11:6 (http://en.wikisource.org/wiki/Bible_(King_James)/Genesis#11:6, "And the Lord said, Behold, the people is one, and they have all one language; and this they begin to do: and now nothing will be restrained from them, which they have imagined to do", do you really think that nothing will be retained from human beings? "Supposedly", people are able to do what they are designed (by God) to be able to do. People can't fly by just imagination. People can't run faster than light by just imagination. People can't live forever by just imagination. So what is God afraid of?

My next questions are: How many people are involved in building the Tower of Babel and what is the percentage to the whole population? Did God only change the languages of the construction workers? Did God change the languages of people who were not involved in the building of the tower? How many languages did God created for this incident? If someone is a construction worker who is not involved in the Tower of Babel, did God change his/her language? If a father's language is changed, Did God also change the language of his wife and children? For each language, is that at least one medical doctor to take care of the sick people?
